Overall I really enjoyed my stay at this Airbnb. It was great being so close to a metro/Sky Train stop, which made travelling around the city really easy. The flat was also spotless and the welcome snacks/drinks were much appreciated. Alex was also a great host, being super communicative and arranging the pickup/drop-off of keys really easily.
There were only two things I would draw to the attention of future renters. There are some pretty scary looking signs in reception about how daily/weekly rentals in this block are illegal, which did put me on edge when I was first arriving. Luckily no one said anything to me throughout my stay, and Alex assured me it was all just a scare tactic, but it was probably one less thing I needed when first arriving into Bangkok.
Secondly, it wasn't the quietest room in the world - I 100% understand that it is a major city and it's something to expect, but not only was it noises from the outside but also buzzers/alarms of adjacent flats that kept going off which disturbed me during my stay. Earplugs did solve the problem but it's just something else to be aware of.
To reiterate, neither of these things are Alex's fault, he was a great host throughout my entire stay, but they are things I would have liked to have known about had I been booking a stay later on.
